  • 1.  X440 Stack occasionally break and end up with two masters

    Posted 06-16-2016 11:41
    The SSH client available on EXOS stops working for the current session after executing the Python script "mlag_config_check.py" (from https://github.com/extremenetworks/ExtremeScripting/tree/master/EXOS/Python/mlag_config_check). Logging out and then back in again resolves the issue.

    The same happens after running the script "show_port_vid.py" (from https://github.com/extremenetworks/ExtremeScripting/tree/master/EXOS/Python/show_port_vid), so it seems to be a problem with running (Python) scripts, not with the individual script that first showed the problem.

    Reported here as asked on https://github.com/extremenetworks/ExtremeScripting .

    Observed on an X620-16t switch with EXOS version 21.1.1.4-patch1-2.

    Maybe you should use the recommended version for the x440. Follow the link

    http://documentation.extremenetworks.com/hw_sw_compatibility/HardwareSoftwareCompatibility/r_exos-re... It must be Version 15.6.4.2-patch1-6.xos

    Check if there are some rx or tx errors on the uplinks:

    sh port stack-ports rx

    sh port stack-ports tx
